Quick lets you type in a family name, basic ID, kiosk ID, phone number (full or partial) or e-mail address (full or partial) and finds the associated people.
See everyone in system displays all people filtered by Groups, People types, status and Team.
People on lists shows people who are on one or more of the lists that you select. (This option is not available if you have not set up any lists.)
Recently viewed people brings up people who have been opened by you or another VSys One user, with the most recently viewed person at the top. If VSys One security is enabled, you'll only see the people that you most recently opened; otherwise this list of recent people is shared by all users. This option is only available if tracing is enabled.
